VALUEUNIT
V(ESD)Electrostatic dischargeHuman body model (HBM), per ANSI/ESDA/JEDEC JS-001, all pins(1)±4000V
Charged device model (CDM), per ANSI/ESDA/JEDEC JS-002, all pins(2)±1500
(1) JEDEC document JEP155 states that 500V HBM allows safe manufacturing with a standard ESD control process.
(2) JEDEC document JEP157 states that 250V CDM allows safe manufacturing with a standard ESD control process.
